OTT SE 200, Operating Instructions Manual

Page: 10 / 28

5.4 Connect the SE 200 to the LogoSens 2 via the 4 … 20 mA
interface
䡵
Connect the SE 200 as shown in Figure 7 to the LogoSens 2 Station M anager
using the connecting cable.
Please follow the LogoSens 2 Station M anager operating instructions as well.
Configuring the LogoSens 2 for SE 200 with the 4 … 20 mA
interface
䡵
Create a LogoSens 2 channel using the I 4-20 mA function block
( Analog Sensors tab).

Connection terminal of the SE 200
䊳
Sensor lag time (s) 0
no lag time necessary
䊳
Error code if range overflow If necessary: Recording error codes
when measuring ranges are exceeded
䊳
Auxiliary sensor supply via relay Not necessary in connection
contact at terminal block
䡵
Insert a 2-point scale function block and make the appropriate settings
(e. g. for an SE 200 with a 10 m measuring range and level measurement:
Point 1: 4
→
0 ; Point 2: 20
→
10).
䡵
In the Channel function block, adjust to the required units and number of digits
after the decimal point.
